Having a baby comes with plenty of new tasks and adjustments. Pumping may not need to be immediately part of the equation. Milk supply adequacy is often an anxiety-driven reason to implement pumping right away, having that visual of milk as reassurance. Unfortunately, pumping output is not a great gauge for total milk supply, especially not in the first days postpartum, and can worsen any anxiety already present. On the flip side, with pumps becoming more efficient than ever, it may create an oversupply if feeding at the breast AND pumping, telling the body to create milk for more babies than there actually is/are. Supply is demand-driven.
